ROAD TRAFFIC NOISE INFLUENCED BY ROAD BUMPS
Journal of Sound and Vibration, 2002Noise levels from different kinds of vehicles were measured on streets close to road bumps. In comparison with free flowing traffic, the acceleration after road bumps increased peak noise levels from 1 to 13 dB (A) max. Although the results are of a pilot nature, it is suggested that noise consequences should be included in the planning of road bumps.

Numerical simulation of tyre/road noise
2011In modern society, traffic noise has become an important issue for mental health. A significant contributor to this noise pollution is exterior tyre/road noise, which is caused by the interaction between tyre and road surface and. In order to reduce tyre/road noise at the source, accurate numerical prediction models are needed. This research deals with

Reviews of Physics in Technology, 1972
Following the publication of the Wilson report in 1963 much attention has been drawn to solving problems connected with road traffic noise. In this article the relevant noise level standards are described and the phenomenon of noise from individual vehicles and taffic as a whole is discussed.

Road traffic noise annoyance in Amsterdam
International Archives of Occupational and Environmental Health, 19853445 persons living in Amsterdam (1507 male and 1938 female), aged 41-43 years, participated in an investigation in which the relationship was studied between the (measured) road traffic noise in front of the houses in which the participants lived, and the (reported) resulting annoyance and sleep disturbance.

Review of road noise corrections in New South Wales road noise assessment method
The Journal of the Acoustical Society of America, 2023Road noise assessments are coming under increased scrutiny from regulators as a result of intensified urban development in New South Wales (NSW), Australia. This paper presents a summary of road assessment methodology, an assessment of the assumptions used in their calculations (particularly as applied to NSW) and some of their limitations. An analysis

Transfer Path Analysis of Road Noise: Overview and Customized Approaches for Road Rumble Noise
SAE Technical Paper Series, 2010<div class="section abstract"><div class="htmlview paragraph">The purpose of this paper is to experimentally analyze structural-borne contributions of noise, vibration and harshness during tire rolling, also called Road NVH, in a passenger vehicle using energy transfer path analysis method (TPA), applied in a case study.

Maximum noise levels in road traffic noise
Journal of Sound and Vibration, 1988Certain field investigations have shown that the correlation between the extent of annoyance due to road traffic noise and the noise dose expressed in leq is rather poor. A higher correlation was found when the expression of the noise dose was based upon the maximum noise level (mnl) from the single noisiest event. To determine the relation between leq

Managing Road Transport Noise through Control of Tire-Road Noise: An Indian Scenario
SAE Technical Paper Series, 2012<div class="section abstract"><div class="htmlview paragraph">The traffic noise has been a major source of discomfort to people for decades. Traffic noise is by far the most pervasive of all noises and over 80 million people are exposed to traffic noises of unacceptably high levels in the European Union alone.
